The interstate highway. This landmark enterprise of the 1950s literally changed the face of America for eternity. In 1919, Dwight D. Eisenhower needed sixty-two days to travel from Washington, D.C., to San Francisco. Now, eighty years and 42,500 miles of paved roads later, the trip can be made in less than seventy-two hours.

Divided Highways is the fascinating history behind the efforts to make cement trails across America, told through the stories of the people who dreamed up, mapped out, paved -- and even tried to stop -- the interstate highways. Popular historian Tom Lewis details man's triumph over nature in an engaging, sweeping style. Award-winning film director Ken Burns says: "He tells the story of how we get from point A to point B in America. And just as our lives should be, Lewis makes the journey more interesting and meaningful than the destination".
